Part of: Japan’s Golden Week, a series of four public holidays in the span of a week that sees offices closed, trains and planes packed and a mass exodus from the major cities like Tokyo.

Who died? Former Japanese Emperor Hirohito, posthumously referred to as Emperor Showa.

They changed his name? Showa refers to the era of Hirohito’s reign. After death, Japanese emperors were referred to by the name of the era during which they ruled. The Showa Emperor’s reign lasted from 1926 to 1989, the longest era in Japanese history. Showa can be translated as “enlightened peace.”

… wasn’t he the ruler during WWII? Hirohitochose the name “showa” for his era after returning from the post-WWI battlefields in France and witnessing the devastation there. His anti-war sentiment seems to have been legitimate, but he ended up reigning over a period of unprecedented military brutality. However, he also reigned over a period of unprecedented economic growth in the years after the war.

How is the holiday celebrated now? Officially it’s a time to reflect on the era of Hirohito’s reign, Japan’s turbulent past and subsequent recovery, and where the country is headed. In reality, as the start of Golden Week, it’s when most Japanese take off for a vacation.

Other ways to celebrate: Public lectures talking about Japan’s participation in the war, to pass on the memories to future generations.Why was it Greenery Day before? Until 1989, the April 29 holiday was still referred to as the Emperor’s Birthday. But when Hirohito died, the Emperor’s Birthday was necessarily moved to December, when his son and successor Akihito was born. Hirohito loved nature, so April 29 became Greenery Day, which allowed people to acknowledge Hirohito without expressly using his name. This actually isn’t the first time this has happened in Japan. The Meiji Emperor’s birthday was celebrated on November 3 until his death in 1912, and after November 3 became Culture Day.

What happened to Greenery Day then?In 2005, Japan passed a bill that turned April 29 into Showa Day. Greenery Day was moved to May 4.

Why? They see the holiday as honoring Hirohito, who reigned during an era of Japanese war crimes and occupation of their countries. Japan argues it that the holiday is a time to reflect on those turbulent times, not celebrate them.

What else is going on during Golden Week? Besides Greenery Day, there is also Constitution Memorial Day on May 3, which is meant to have people reflect on the Japanese government. May 5 is Children’s Day, a day to celebrate the happiness of being a kid. Traditionally, families fly carp-shaped flags to bring good luck to their boys. Girls don’t get any flags, fish-shaped or otherwise.

These aren’t really “party time” holidays, are they? Last time, we covered Songkran, Southeast Asia’s annual drunken water fight. This time, we have a series of holidays that encourage reflection on, chronologically, a nation’s past and future, man’s place in nature, the meaning of democracy, and the innocence of children.They are decidedly not party time holidays, but that’s hardly a bad thing. You can have a party anytime. But when’s the last time you thought about the importance of effective governance and the dictates of post-war economic recovery? That’s what I thought.
